Outdoor OG Kush Auto - 1st time

This week has returned to being rainy and quite humid again. The previous week was glorious and I noticed two interesting things happen: 1) Finally some side branches growing 2) Root protruding above the soil I added a layer of soil on each of the plants to cover them. I also have kept up with a couple of light feedings of the Jacks bloom fertilizer. These OFK continue to be quite frosty looking (like my Amnesia Haze are too). They all seem behind where the 10-week autoflower calendar would put them. If that schedule holds true, I would be harvesting in just under two weeks. That just seems too soon based on how small the buds are. Buds on all my plants look quite small and I am sure it's a result of the less-than-optimal amount of direct sun they receive. This is probably 5 hours per day. Maybe the rain and cold weather we’ve had has slowed them down a bit. I’d love to think that they may get 3 weeks more of growth vs. the two weeks that the calendar indicates… I will say that out of my 3 varieties, the OGK is probably the farthest along and has the best looking buds so far. The stigmas are all 99% white. I am just noticing a few that are turning slightly darker. I'm hoping for continued bud growth. The two OGK plants 30 and 27 inches tall (only about 2" of growth in the past week). While this is my 1st grow, I have to assume the smell is "normal" now. (I have nothing to compare this to.) Just maintaining and hoping for more dry weather in the future!
